Patent FR-2378621-A1 (FR)
Title: Welding thick walled liquid filled thermoplastic sachets - using hot strip welding tool
IPC: B65B51/30
Filed: 1976-11-04
Abstract: A welding tool for sealing thermoplastic saches contg. liquids comprises jaws which close horizontally. One jaw is covered with an electrically insulating refractory coating and supports a hot strip of curved cross-section, convex face outwards. The other jaw is faced with a heat resistant rubber block. Both jaws are fitted with ancillary pillar for dispensing thin PTFE film to mask the welding bar and the jaw faces. Suitable for welding thick walled sachets, contg. e.g. oils, using relatively short cycle times. The low thermal inertia of the jaw coating and the film allow high energy heating pulses to be used, because the adjacent surfaces can be cooled efficiently between cycles. The high strip energy and the renewable film covers suppress problems due to chance splashing and soiling of the welding tool faces.

Title: Disc brake with central support bracket - has split-casing secured by bolts on either side of support plate attached to bracket
Inventor: ESPARCIEUX PIERRE
IPC: F16D55/228
